초록
Cordierite glass ceramic has become an electronic substrate material for electronic circuits and the use of whiskers for improving strength and toughness is evident. Green sheets of mixtures containing 15% silicon nitride were sintered to greater than 99 % density. The microstructure was analysed using optical microscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD). The toughness and hardness were improved with increasing the whisker vol. % and sintering temperature. Especially, it is assumed that toughening increasing at the more high sintering temperature relevants to the glass phase increasing, as showned in the roughness of the fracture surfaces. It was directionally dependent of whisker direction during processing.
